分布式发电(distributed generation, DG)是一种高效、清洁的发电方式，以其具有投资少、发电方式灵活、可与环境兼容等优点，在微电网中得到了广泛的应用。但是，在向配电网引入分布式发电的同时也带来了一些问题。在微电源并入电网时，如果在并入过程中微电源出现单相、两相或三相故障，就会对电网的稳定性带来不利的影响。通过Matlab软件，建立仿真实验平台，针对以上故障问题进行了仿真分析。%Distributed generation was a kind of efficient and clean way of generating. Low investment and flexible power generation could be compatible with the environment were its advantages. It was widely used in the micro-grid. However, the introduction of distributed generation to the distribution network would bringing some problems. When the micro power source connected to power grid, in the course of connection, if has the single phase and two phase or three phase fault occurred in power source, the stability of the power grid was influenced. The establish of the simulation experiment was based on the MATLAB software, and the simulation analysis would carry out on the above problem.
